The Journal of nutrition, 143(7), 1046-1051 (2013-05-24)
In mammals, nicotinamide (Nam) is biosynthesized from l-tryptophan (l-Trp). The enzymes involved in the initial step of the l-Trp→Nam pathway are l-Trp-2,3-dioxygenase (TDO) and indoleamine-2,3-dioxygenase (IDO). We aimed to determine whether tdo-knockout (tdo(-/-)) mice fed a diet without preformed niacin

Nicotinic acid (NA), or niacin, lowers circulating levels of lipids, including triglycerides, very low-density lipoprotein-cholesterol, and low-density lipoprotein-cholesterol. The lipid-lowering effects have been attributed to its effect to inhibit lipolysis in adipocytes and thus lower plasma free fatty acid (FFA)

Nutrition reviews, 70(6), 357-366 (2012-06-01)
Elevated low-density lipoprotein cholesterol (LDL-C) has been the main target of lipid-altering therapy to reduce cardiovascular risk associated with dyslipidemia. Residual cardiovascular risk remains, however, after achievement of goal LDL-C levels and is associated in part with other risk markers
